In this paper, we describe a system called Glean, which is predicated on the idea that any coherent text contains signi cant latent information, such as syntactic structure and patterns of language use, which can be used to enhance the performance of Information Retrieval systems. We propose an approach to information retrieval that makes use of syntactic information obtained using a tool calle...

Geospatial semantic graphs provide a robust foundation for representing and analyzing remote sensor data. In particular, semantic graphs support a variety of pattern search operations that capture the spatial and temporal relationships among the objects and events in the data. However, in the presence of large data corpora, even a carefully constructed search query can return a large number of ...

Logarithmic search motion estimation is popular in video codecs because of its low complexity, and because it finds the motion vector in a pre-defined number of computation steps. Motion estimation still remains the most demanding part of the encoding scheme, so further improvements in terms of reduced computational complexity are desirable. Motion estimation is also rewarding, in terms of bit-...

In this paper we consider the problem of finding sets of points that conform to a given underlying model from within a dense, noisy set of observations. This problem is motivated by the task of efficiently linking faint asteroid detections, but is applicable to a range of spatial queries. We survey current tree-based approaches, showing a trade-off exists between single tree and multiple tree a...

This paper presents a method for understanding personal ways of thinking and doing in daily lives among different countries by mining their ways as patterns in a sense of pattern language. Pattern language is a methodology of describing tacit practical knowledge, where each pattern consists of context, problem, and solution. In this paper, patterns mined from the workshops we held in the follow...

This paper reports a research effort in Information Extraction, especially in template pattern matching. Our approach uses reach domain knowledge in the football (soccer) area and logical form representation for necessary inferences of facts and templates filling. Our system FRET' (Football Reports Extraction Templates) is compatible to the language-engineering environment GATE and handles its ...

We have searched the 1st-year WMAP W-Band CMB anisotropy map for evidence of cosmic strings. We have set a limit of δ = 8πGμ/c < 8.2× 10 at 95% CL for statistical search for a significant number of strings in the map. We also have set a limit using the uniform distribution of strings model in the WMAP data with δ = 8πGμ/c < 7.34 × 10 at 95% CL. And the pattern search technique we developed here...

well-known seismic design codes have offered an alternative equivalent static procedure for practical purposes instead of verifying design trials with complicated step-y-step dynamic analyses. such a pattern of base-shear distribution over the building height will enforce its special stiffness and strength distribution which is not necessarily best suited for seismic design. the present study, ...

Now, we come to offer you the right catalogues of book to open. flexible pattern matching in strings practical on line search algorithms for texts and biological sequences is one of the literary work in this world in suitable to be reading material. That's not only this book gives reference, but also it will show you the amazing benefits of reading a book. Developing your countless minds is nee...
